What exactly are mini strokes? They’re tiny lapses in blood flow to the brain also known as TIAs, or transient ischemic attacks.

Mini strokes can result from blood clots or from narrowed or injured vessels that supply blood to the brain. The resulting stroke-like symptoms typically resolve after an hour or two.

While they’re not fatal, a 2011 study by Australian researchers found they can shorten your life. They also boost the risk of a full blown stroke.
